What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Maen Manhattan 40

Owners appreciate the Maen Manhattan 40's thin case and unique dial, with some finding its proportions too large for smaller wrists. One owner noted a snagging crown and difficult winding action. Accuracy figures vary, with one owner reporting +18s/d to +24s/d on the 37mm version, while another owner of the 40mm model did not specify accuracy. On balance, owners and reviewers find the Maen Manhattan 40 to be a good value, with its thinness and dial finishing being key strengths.

Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition

The Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition is praised for its beautiful design and refinement over previous models, featuring vertically textured glacier-inspired dials. Owners, however, consider the €1500 RRP too high, suggesting a price closer to €900-€1000, noting the aluminum bezel insert instead of ceramic. Some owners report the 6R movement runs slow. On balance, owners find the Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition beautiful and a refinement, but the price and aluminum bezel are points of contention.
